Vavu Yosabwerera ya Mapaipi a Mafuta, Gasi ndi Chemical

Diskiyo imakwera molunjika kuchokera pampando pamene kupanikizika kumabwera, kenako kumabwereranso paokha pamene mzerewo ulibe kanthu. Kulibe akasupe kapena mahinji mapini kuti mutope komanso palibe kulongedza kuti kutayike, ndichifukwa chake imagwira mwamphamvu pa nthunzi, chakudya cha boiler ndi mautumiki ena pomwe ma cheke wamba amacheza kapena kudontha pakapita nthawi.

Zimabwera zokhala ndi nsonga zopindika zomwe zimakhazikika pamzere. Kwa mainjiniya oyendetsa madzi, nthunzi kapena mpweya omwe amangofuna valavu ya cheke yomwe amatha kuyiwala ndikuyiwala, ichi ndi chosankha cholunjika.

Zomwe valve yoyendetsa galimoto imachita

Imayimitsa kubwerera. Pampu ikatsekeka, chingwe chimadetsa nkhawa, kapena valavu imatsekeka patsogolo panu, madzimadzi amakankhira chammbuyo ndipo amatha kuzungulira mpope mobwerera, nyundo mita, kapena kutaya madzimadzi komwe sikuyenera. Valve yowunikira imayimitsa zonsezi isanayambe: kuyenda kutsogolo kumakweza diski pampando, ndipo mphindi yomwe imatuluka, diski imagwera mmbuyo ndi mphamvu yokoka ndikusindikiza mzere.

Makhalidwe Ofunika

Momwe mungapangire cheke chokweza ndi chosiyana

Chimbale chimayenda molunjika mmwamba ndi pansi, kukwera njira yothamanga

Imatseka ndi mphamvu yokoka, kotero palibe kasupe wa kutopa ndipo palibe pini ya hinge yotha

Kuchepa kwa magawo osuntha kumatanthauza kusakonza bwino komanso kuchepera komwe kungalephereke pakatha zaka zambiri

Zimayenda mwakachetechete pa chakudya cha nthunzi ndi chowotchera, pomwe macheke odzaza masika amakonda kucheza

Kuyenda kwakanthawi komanso kuchitapo kanthu mwachangu kumachepetsanso chiwopsezo cha nyundo yamadzi pakusintha kwadzidzidzi

Chimapangidwa ndi chiyani

Thupi : Chitsulo cholimba cha kaboni, chopangidwa kuti chitenge ma spikes opanikizika ndikuzungulira mobwerezabwereza / kutseka popanda kusweka

Chimbale & mpando : zofananira ndi ntchito yanu yaukhondo, yotseka yotseka; chepetsa zosapanga dzimbiri zopezeka kutentha kwambiri kapena zowononga pang'ono

Valavu iliyonse imasindikizidwa ndi nambala ya kutentha, kalasi yazinthu, kukula kwake ndi kalasi yopanikizika, kotero mutha kuzitsatira kuchokera ku mphero yachitsulo kupita ku mzere wanu. Ma MTC amaperekedwa ndi oda iliyonse.

Kulumikizana ndi kukhazikitsa

Bawuti wopindika molunjika pamzere; nsonga za ulusi zomwe zilipo kuti zitheke, njira yolumikizira

Imakwera bwino m'mizere yowongoka, chifukwa chimbale chimayenda m'mwamba ndi pansi osati kutembenukira cham'mbali

Standard nkhope RF / RTJ; palibe kuwotcherera kofunikira - tsegulani ndikukweza valavu pokonzanso

Kumene amapezerapo kusunga

Chakudya cha nthunzi ndi chotenthetsera (gawo lapamwamba loyang'anira zonyamula), makina apanikizidwe a mpweya, madzi ndi madzi oyeretsera omwe sayenera kuyenda cham'mbuyo, mizere yotulutsira pampu yomwe ikufunika kutetezedwa kuti isatembenuke mobwerera, ndi mapaipi anthawi zonse akumafakitale pazantchito zosawononga.

Zolemba zaukadaulo pang'ono

Kukula kosiyanasiyana: DN15 - DN400, yokulirapo popempha

Kuthamanga mlingo: PN16 / PN25 / PN40, kapena ASME Kalasi 150 / 300 / 600

Kulumikizana: flanged (RF / RTJ) kapena ulusi

Thupi zakuthupi: chitsulo cholimba cha kaboni, A105 / WCB ndi ena

Media : madzi, nthunzi, mpweya woponderezedwa, zamadzimadzi zoyera zosapsa

Miyezo : API, ASME ndi miyezo yofananira ya GB

Mavoti enieni amatsimikiziridwa motsutsana ndi ma TV anu, kuthamanga ndi kutentha - sitikugwirizana ndi mtundu wamtundu wanu.

Momwe mungasankhire zinthu

Mpweya, madzi kapena mpweya woponderezedwa umatiuza ngati mukufuna nyumba yotentha kwambiri; kaya ndi zowononga zimasankha ngati tisinthana ndi chepetsa kuti zisawonongeke; kuthamanga ndi kutentha zimasankha thupi ndi mpando kalasi. Titumizireni media yanu, pH ndi kuchuluka kwa kutentha komwe kumagwirira ntchito, ndipo uinjiniya udzakuphatikizani njira yotsika mtengo kwambiri kwa inu.

Quality, chitsimikizo ndi kutumiza

Valavu iliyonse imadutsa chipolopolo cha hydrostatic ndi kutayikira kwa mipando isanatumize, ndipo kuwunika kwa mboni za chipani chachitatu kumathandizidwa. Ma MTC, malipoti oyesa, zojambula zamitundu ndi buku la opareshoni zimabwera ndi dongosolo. Malekezero a Flange ndi ulusi amatetezedwa kuti azitha kuyenda, ndipo makulidwe achitsulo cha kaboni amasungidwa kotero kuti mitundu yopangidwa ndi ulusi imatumizidwa mwachangu.

Zomwe zimatisiyanitsa

Ambiri ogulitsa amatumiza chipolopolo cha hydrostatic satifiketi ndikuchitcha tsiku. Timagawananso lipoti loyesa kutayikira kwa mpando, chifukwa ndiye nambala yomwe imakuwuzani ngati valavu imagwira. Ndipo pa chakudya cha nthunzi kapena chowotchera, tikupangira kuti muchepetse ntchito yanu yeniyeni m'malo mongokankhira mtundu wamba.

Mafunso omwe amafunsidwa pafupipafupi

Q1. Kwezani cheke vs swing cheke?

Chimbale chokweza cheke chimayenda molunjika mmwamba ndi pansi ndikutseka ndi mphamvu yokoka; cheke chogwedezeka chimayenda pa hinge. Mtundu wokwera umasindikiza bwino kwambiri pa chakudya cha nthunzi ndi chowotchera, pomwe mtundu wa swing uli ndi kutsika kotsika kwa mizere yayikulu, yothamanga kwambiri.

Q2. Kodi ikhoza kukhazikitsidwa molunjika?

Inde. Chifukwa chimbale chimayenda mmwamba ndi pansi, kukwera koyima kumafanana ndi njira yake yotseka yachilengedwe; kuyika kopingasa kumagwiranso ntchito.

Q3. Kodi pali mtundu wodzaza masika?

Inde. Mtundu wokhazikika umatseka ndi mphamvu yokoka; kwa mizere yotsika kwambiri yomwe imafunikira kuyandikira mwachangu, kovutirapo, timawonjezera kasupe kuti tithandizire diski.

Q4. Kodi zimayambitsa nyundo yamadzi?

Diski yokweza imatseka mwachangu ndikuyenda kwakanthawi kochepa, komwe kumathandiza kuchepetsa kuthamanga kwapambuyo. Mipando yathu ndi yoyezetsa kutayikira, kotero ikatsekedwa imakhala yolimba.

Q5. Kodi ndikufunika kuwotcherera kuti ndiyike?

Ayi. Mabaibulo a Flanged amakwanira gasket ndikuwongolera mabawuti; zomasulira za ulusi wononga molunjika. Mukakonzanso, mumatsegula ndikukweza valavu popanda kudula chitoliro.

Q6. Kodi mungandipatseko ziphaso zakuthupi?

Inde. Ma MTC, malipoti oyesa, zojambula zazikulu ndi sitima yapamadzi yoyendetsedwa ndi dongosolo, ndi kuwunika kwa mboni za gulu lachitatu zilipo.

Q7. Kodi nthawi yotsogolera ndi chiyani?

Standard carbon zitsulo kukula kwake ndi katundu ndi sitima mofulumira; zinthu zopanda muyezo kapena gulu lamphamvu lapadera limafunikira nthawi yopanga - tumizani zolemba ndipo timatsimikizira.

Q8. Kodi ndingapeze chitsanzo kuti ndiyese kaye?

Inde. Timathandizira maoda azitsanzo pamiyeso yokhazikika kuti mutsimikizire musanatenge zambiri, kutsitsa chiwopsezo chanu chosankha.
